SHUTTER-WORKER.

SPECIFICATION forming` part of Letters Patent No. 443,709, datedDecember 30, 1890.

Application tiled May 20, 1890. Serial No. 352,529. (No model.)

T all whom t may concern:

Be it known that we, HENRY D. DEsoHLER and EDMUND H. FRETZ, citizens ofthe United States, residing at Emaus, in the county of Lehigh and Stateof Pennsylvania, have invented a new and useful Shutter-Bower, of whichthe following is a specification.

This invention relates to shutter-bowers, and the object thereof is toprovide means 1o whereby the shutter may be operated from within thehouse without raising thewindow, and may be set at any desired angle andlocked in such position. This object we accomplish by our invention,which consists of a special arrangement and adaptation of the well-knownrack and pinion, said rack being located within a half tube or gutterpassing through the window-frame, and also provided with pins whichengage notches in said gut- 2o ter to hold it set at any desiredposition therein, and of certain details and auxiliaries ofconstruction, all as hereinafter more fully described, and asillustrated in the drawings, in which- 2 5 Figure l is a horizontalsection through a portion of a window-frame, showing our improvedshutter-bower in position with the shutter closed. Fig. 2 is a plan viewof the rack and pinion in position to lock the shut- 3o ter open. Fig. 3is a front elevation of the shutter-bower.

Referring to the said drawings, A is the leaf of the lower hinge,supporting an ordi` nary shutter, which leaf has a gear-wheel or 3 5pinion A surrounding its pintle. The other leaf of the hinge B issecured to the windowframe and carries the pintle B', and extending fromthis leaf is a tube C, which passes into the window-frame, as shown, andthe upper side of which is out away, as at c, forming a gutter orhalf-tube. Through the tubular portion C moves a rack D, whose teethengage those of the pinion, and pivoted to the inner end of this rack isa bar D', iitting loosely within the gutter c,extending through theframe into the interior of the house and there provided with a handle orknob E.

The relative arrangement of parts is such that when the shutter isclosed, as shown in Fig. l,the knob E stands against the window- 5oframe, and the joint between the rack D and bar D stands just inside theinner end of the tube C. We provide the gutter c with a number ofnotches hin its upper edge, and through the bar D is seated a pin g,which is adapted to engage these notches. By having several sets ofnotches it will be readily -seen that the shutter may be bowed, openedcompletely, or closed tightly, and locked in any of these positions byengaging the pin in 6o certain of the notches. The pin is of coursedisengaged from the notches by raising the knob E, the hole through theinner face of the window-frame being of a shape and size to permit suchraising, as will be readily understood.

In a shutter-bower, the combination, with the shutter having a pinion onits hinge-leaf around its pintle and a tube extending 7o through thewindow-frame and forming the other leaf of the hinge, the upper half ofsaid tube being cut away for a portion of its length and provided withnotches in its upper edges, of a rack-bar moving through said tube andengaging said pinion, a bar pivoted to said rack-bar and moving in saidhalf-tube, a knob on the inner end of said bar, and a pin through thebar engaging certain of said notches, substantially as described. 8o

In testimony that We claim the foregoing as our own we have heretoaffixed our signatures in presence of two witnesses.
